Here are some of the most critical tips to keep in mind when optimizing your site's pages :

Site Speed : This is one of the few search engine ranking signals that you can control. So make sure you're doing everything you can (taking advantage of server caches, fast web hosting and uncluttered code) to make your site load as fast as lightning.

Outbound Links : Outbound links show Google and the other search engines that your site is a hub that gives people the information that they're looking for. Consider adding one outbound link for every 400 words of content.

Unfortunately, most on-page SEO tutorials focus on ranking signals from 1999. This updated on-page SEO infographic from Brian Dean of www.Backlinko.com help illustrate the skill to modern day webmasters and SEO.
